Recent estimates predict that between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations. This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share.If the estimates above are accurate, which of the following conclusions can be drawn?
(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.
(B) In 1995 more people will be working in high-paying service occupations than will be working in low-paying service occupations.
(C) Nonservice occupations will account for the same share of total employment in 1995 as in 1982.
(D) Many of the people who were working in low-paying service occupations in 1982 will be working in high-paying service occupations by 1995.（A）
(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.
低收入的人数增加了，但是总体收入群体中，却是高收入的比例增加了。说明高收入的人数增加的更多。
看了讨论贴还是不明白，应该是B啊，怎么是A呢。晕了。。。救命。
借助数学方法表示可能容易理解一点
低收入人群增加，所占的share没有增加，说明总样本基数增加了，总样本增加数/总样本基数>=低收入人群增加数/低收入人群基数；s/S>=l/L
总样本基数增加了，高收入人群所占share增加了，说明高收入人群增加数/高收入人群基数>总样本增加数/总样本基数； h/H>s/S
then，高收入人群增加数/高收入人群基数>总样本增加数/总样本基数>=低收入人群增加数/低收入人群基数; h/H > (s/S) >=) l/L
i.e. L/l> H/h
Meanwhile，低收入人群增加最厉害，l>h, 加上上一个条件 L/l > H/h
那么必然最初是 L>H 才有可能
B的话~从文中所给无法很直接的得出结论~因为working employee的数量与基数是有关的~就基本能判断是混淆项~
再根据之上对A项是正确项的推断，L>H,l>h， L+l>H+h,发现根本是个错误项。
其实GMAT有时候真的就是靠直觉，不会要你饶太多弯想太多~想到第一步的时候基本就确定了
谢谢解释。
明白一点了。
脑袋清醒的时候再看看。。。谢谢
